PROBLEM TO BE SOLVED: To provide an airbag, the development time of which is sufficiently short, and which drastically reduces a possibility that an abdominal part or a chest part of a rear seat occupant is injured.SOLUTION: An ar bag for a rear seat occupant is included in a back part of a driver seat or a front passenger seat and developed toward a rear side of the back part. The airbag comprises: a hollow cylindrical left area in which an axial direction of a shape of the area at the development time is extended in an approximately horizontal direction, and a vertical cross-sectional shape approximately perpendicular to the axial direction is annular; a hollow cylindrical central area with partially lacked part in which an axial direction of the area is extended in an approximately horizontal direction, and a vertical cross-sectional shape approximately perpendicular to the axial direction is a partially lacked annular shape; and a hollow cylindrical right area in which an axial direction of the area is extended in an approximately horizontal direction, and a vertical cross-sectional shape approximately perpendicular to the axial direction is annular. A partially lacked area of the partially lacked hollow cylindrical type of the central area is an area from the vicinity of a lower end to the vicinity of a rear end.SELECTED DRAWING: Figure 1
【課題】展開時間が十分に短く、且つ、後部座席乗員の腹部ないし胸部に傷害が発生する可能性が顕著に低減されたエアバッグを提供すること。【解決手段】本発明は、運転席または助手席の背部に内蔵され、当該背部の後方側に向けて展開するようになっている、後部座席乗員のためのエアバッグであって、展開時の形状が、軸方向が略水平方向に延びると共に当該軸方向に略垂直な鉛直断面形状が環状である中空筒型の左領域と、軸方向が略水平方向に延びると共に当該軸方向に略垂直な鉛直断面形状が一部欠けた環状である一部欠けた中空筒型の中央領域と、軸方向が略水平方向に延びると共に当該軸方向に略垂直な鉛直断面形状が環状である中空筒型の右領域と、を有しており、前記中央領域の前記一部欠けた中空筒型の一部欠けた領域は、下方端近傍から後方端近傍までの領域であることを特徴とするエアバッグである。【選択図】図1
